Title: Reflection preuentine device for optical guide and semiconductor laser to which that is applied
Inventor: JIYANNMARUKU BERUDEIERU
IPC: G02B1/11
Filed: 1990-02-22
Abstract: PURPOSE: To remove stray reflection by inclining an input plane in the direction of an incident beam so that 1st and 2nd Fresnel reflectance coefficients can have the same absolute value, and making a reflection preventing layer thick enough for generating the reflected light of an opposite phase on 1st and 2nd boundary planes. CONSTITUTION: A surrounding medium 45 is separated from a guide medium 100, and the input plane to receive an incident beam 200 is covered with a reflection preventing layer 32 composed of a material having a 3rd refraction factor. Then, the input plane is inclined in the direction of the incident beam 200 so that the 1st Fresnel reflectance coefficient on a 1st boundary plane 38 separating the surrounding medium 45 and the reflection preventing layer 32 and the 2nd Fresnel reflectance coefficient on a 2nd boundary plane 41 separating the reflection preventing layer 32 and the guide layer 100 can have the same absolute value. Besides, the reflection preventing layer 32 is made thick enough for generating the reflected light of the opposite phase in the reflection of the incident beam 200 on the 1st and 2nd boundary planes 38 and 41. Thus, effective reflection prevention is enabled.

Title: Semiconductor integrated circuit device
Inventor: TOKUMARU SEIYA
IPC: H01L21/74
Filed: 1981-03-24
Abstract: PURPOSE:To integrate I<2>L, a linear element and a bipolar element on a single substrate by selectively forming a buried layer having the structure of laminating or a single layer to the Si substrate and an epitaxial layer under an active  region. CONSTITUTION:N<+> layers 4a-4c are buried onto the P type Si substrate 2, the N epitaxial layer 6 is stacked, N<+> layers 8a, 8b are stacked onto the layers 4a, 4b, an N<+> epitaxial layer 10 is laminated, and the epitaxial layers are isolated by P layers 12, 14, 16, 18 reaching the substrate 2. P<+> layers 30, 32 and 50, 52, 60 are formed simultaneously, N<+> layers 38, 40 and 54, 62, 64 are shaped, and the junction regions of the P<+> layer 32 and P layers 34, 36 are used as the resistors of element sections 22, 24. According to this constitution, the amount of holes stored decreases because an N<+> layer 10a is thin in the I<2>L 10, speed is increased, a current amplification factor is augmented, and integration can be heightened. Since an N<+> layer 10b is thin in the bipolar element 22, speed is increased, series resistance is low, and output voltage at the time of saturation is low. With the linear element 24, the epitaxial layer can be laminated in desired thickness, a layer such as a layer 6c is thickened, concentration is kept at low concentration regardless of regions 20, 22, and dielectric resistance can be increased.

Title: Head positioning device
Inventor: KITAGAWA KATSUKI
IPC: G11B21/10
Filed: 1989-02-27
Abstract: PURPOSE:To perform the positioning of a head at high speed and with high accuracy by using an arm of light weight and with low rigidity by providing a sensor to detect deformation, an element to generate a force corresponding to input, and a controller to suppress the deformation. CONSTITUTION:A strain gage 6 detectable a strain and a piezo-electric element 7 able to generate the force to correct the strain are mounted at the side plane of the arm 2. When a device is operated and the strain occurs in the arm 2 in a direction of arrow head in figure, the volume of the deformation of the arm 2 is shown as the change of the resistor of the gage 6. The change of the resistor is detected as a voltage by a bridge circuit 8, and it is applied on the element 7 via a differential amplifier 9, an LPF 10, a phase compensation circuit 11, and a piezo-electric element driving amplifier 12, and the element 7 generates the force required for the correction of the strain of the arm 2. Thereby, since the strain of the arm 2 is suppressed by the deformation in a reverse direction of the element 7, and rigidity for the strain of the arm 2 can be heightened, the mechanical resonance point of the device can be increased equivalently, and the positioning with high accuracy can be performed.

IPC: F02P5/15
Filed: 1985-03-05
Abstract: PURPOSE:To improve combustion performance of an engine at transition time and thereby prevent deterioration of operative performance by installing an idling engine speed controlling mechanism which judges the over-lean or over- rich state in the transitional period and controls by-pass valve in the idling speed control mechanism and ignition time in accordance with the judgement results. CONSTITUTION:CPU 23 judges the lean-rich state of air-fuel ratio at the transitional period based on negative pressure corresponding signals and averaged signals corresponding to surge tank pressure. The engine is put under such transitional period control as to change the opening of the by-pass valve 15 of an idling speed control mechanism 13 in the direction of closure and correct ignition time to be on the spark advance side in the lean state and effect control in the opposite direction in the rich condition. Therefore, the slippage of air-fuel ratio at the transitional period is diminished, and combustion start-up performance is improved due to optimum ignition time. For this reason, defects in operative performance such as decline in rotational speed and engine stoppage at the time of deceleration and hesitation and stumble at the time of acceleration can be successfully prevented.
